While sitting next to my sister in a bar with a bunch of family I happened to notice her nice large tits & cleavage. It dawned on me that her pussy was the first pussy I'd seen touched & explored when we were young. My parents had an older neighbor boy watch us when they went out. He started having us (me 7 & sister 5) hold his dick & play with it. He played with my dick, and we took turns sucking each other. I held his dick while my sister licked & sucked it. We got my sister naked and she willingly did as directed, spread her legs raised her knees & opened her little pussy so we could touch it &look inside. I believe him & me took turns licking it & tasting it. She also licked & sucked our hard dicks. He showed her how to stroke & jack it and we all took turns experimenting with each other. When I was 15 & she 13 I used to wrestle with her when no one was home. I'd playfully pin her down and work my hand down into her pants and feel her nubile pussy that was sprouting hair. I'd slowly work a finger into her then just keep it there and cup her pussy while spooning from behind. I'd pull out my dick and have her hold it and play with it. Never did get to fuck her but always had the fanatasy of doing it, who knows, might happen some day.
